`erc-stamp--deferred-date-stamp' as a permanent-local variable.
(erc-stamp--date): Document expected possible values for `fn' slot.
(erc-stamp--defer-date-insertion-on-post-modify): Use the function
`ignore' to mean a new `erc-timer-hook' member has been requested.
Use nil to mean one has already run. Deferred date stamps are new in
ERC 5.6 and Emacs 30.
(erc-stamp--date-mode): Improve doc string.

`reschedule' function on a timer to avoid growing the stack when
calling `delete-process'.
* lisp/erc/erc-common.el (erc--favor-changed-reverted-modules-state):
Fix `pcase' condition so that changing an option to its standard value
does not earn a "STANDARD" label in Customize if that value differs
from the saved one.

(erc-fill-wrap-disable): Add and remove `erc-stamp--insert-date-hook'
member.
(erc-fill--wrap-continued-predicate): Add function-valued variable for
modules to influence `erc-fill--wrap-continued-message-p', which was
originally introduced as part of bug#60936.
(erc-fill--wrap-rejigger-last-message): Move toward beginning of file.
(erc-fill--wrap-unmerge-on-date-stamp): New function.
(erc-fill-wrap): Use `erc-fill--wrap-continued-predicate'. Restore
recently deleted hunk that reset the wrap marker upon seeing a date
stamp.

* lisp/erc/erc-speedbar.el (erc-speedbar-buttons): Dispatch queries as
if they were channels when `erc--queries-current-p' returns non-nil.
That is, show head counts alongside query targets as users come and
go.
(erc-speedbar-insert-target): Defer to `erc--queries-current-p' to
know whether to show a query in the style of a channel. This affects
both the plain speedbar integration as well as the `nickbar' module
added for bug#63595. Also, use question marks rather than the empty
string for query bullets, so that query and channel items are aligned
vertically.
* lisp/erc/erc.el (erc--queries-current-p): New function.

* lisp/erc/erc-backend.el (erc-server-KICK, erc-server-PART): Use new
function `erc--remove-channel-user-but' instead of
`erc-remove-channel-users'. In `erc-server-KICK', remove sender's
channel membership data after displaying the message so that nicks are
buttonized. Return nil. In `erc-server-PART', don't run
`erc-remove-channel-member' when the client itself has parted.
* lisp/erc/erc-common.el (erc--remove-user-from-targets): New
function.
* lisp/erc/erc.el (erc-remove-server-user): Redo doc string.
(erc--forget-server-user-function): New variable.

value of `erc--forget-server-user-function'.
(erc-remove-channel-user): Defer to `erc--forget-server-user-function'
to do the actual removal.
(erc-remove-user): Defer to `erc--remove-user-from-targets'.
(erc-remove-channel-users): Redo doc
(erc--remove-channel-users-but): New function. The only use case thus
far is for protecting the client's own `erc-server-users' entry from
removal when draining `erc-channel-members' tables after the client
leaves a target buffer or quits.
(erc-kill-buffer-function): Don't remove own user from
`erc-server-users'.
* test/lisp/erc/erc-scenarios-base-renick.el
(erc-scenarios-base-renick-queries-solo): Assert own client parting
its only channel doesn't remove own user from server. Also assert
that another user parting their only channel removes them from all
queries. (Bug#70928)
* lisp/erc/erc-backend.el (erc-server-JOIN): Update query membership
via `erc--ensure-query-member' when someone else joins a channel.
(erc-server-NICK): Update query membership via
`erc--ensure-query-member' after someone else changes their nick.
(erc-server-PRIVMSG): After printing a query message from some other
person, remove their nick's data from the query buffer's user table if
they're "untracked," i.e., not a member of a channel.
(erc-server-263, erc-server-263-functions): New function and variable,
a default response handler and hook for "RPL_TRYAGAIN", which servers
send for things like rejecting "WHO" and "WHOX" responses due to rate
limiting.
(erc-server-311): Fix call to `erc-update-user-nick' so the userhost
login component is no longer supplied as the `info' parameter but
rather, correctly, as the `login'.
(erc--extract-352-full-name): Factor out trailing hop-count and GECOS
parsing for use by overriding handlers or those for adjacent numerics.
(erc-server-352): Refactor to handle asterisk as `channel' parameter,
which indicates a nick rather than a channel target.
(erc-server-366): Update membership in all query buffers via
`erc--ensure-query-members' after all names have been received.
(erc-server-401): Forget a known user completely when the server
reports them as nonexistent.
* lisp/erc/erc-common.el (erc--get-server-user): New function, a thin
wrapper around `erc-get-server-user' for cases were inlining would
require declaring symbols not defined in erc-common.
* lisp/erc/erc.el (erc-channel-members): Mention that instances are
used for query-participant tables as well.
(erc--decouple-query-and-channel-membership-p): New variable, a
compatibility flag to access pre-5.6 query bookkeeping behavior.
(erc--ensure-query-member, erc--ensure-query-members): New functions.
(erc-cmd-QUERY): Ensure parties are present in the query buffer's
membership table if they're known to be on the server by simple virtue
of being present in some joined channel.
(erc-message-english-s352-you): New variable.
* test/lisp/erc/erc-scenarios-base-query-participants.el
(erc-scenarios-base-query-participants)
(erc-scenarios-base-query-participants/legacy): Rename former to
latter. Enable compat flag to activate legacy query behavior in which
channel membership does not impact query membership.
(erc-scenarios-base-query-participants/coupled): New test asserting
new behavior in which channel membership dictates query
membership. (Bug#70928)
* lisp/erc/erc-backend.el
(erc--wrangle-query-buffers-on-nick-change): New function for handling
buffer renaming and message routing triggered by a nick change. Such
twiddling used to reside in `erc-server-NICK' but has been separated
out for use by built-in modules overriding `erc-server-NICK'. The
behavior has also changed to favor always reusing an existing query
buffer whenever possible instead of creating a new, <N>-suffixed
buffer. This addresses some arguably unfinished business from
bug#48598.
(erc-server-NICK): Fix erroneous call to `erc-update-user-nick' that
passed the sender's login as the function's INFO argument. Move
buffer renaming logic to `erc--wrangle-query-buffers-on-nick-change'
for use by "NICK" handlers managed by modules. Also, print the notice
in all query buffers when the client changes its own nick.
(erc-server-QUIT): Show messages in all query buffers when the client
itself quits, but prevent `track' from updating the mode line with
redundant noise.
* lisp/erc/erc.el (erc-generate-new-buffer-name): Fix typo in doc.

`erc-channel-user' object instead of calling accessors.
(erc-speedbar--hidden-speedbar-frame)
(erc-speedbar--emulate-speedbar): Add doc string.
(erc-speedbar--handle-delete-frame): New function.
(erc-speedbar--toggle-nicknames-sidebar): Remove function because its
conditional logic was needlessly complicated and is no longer needed.
(erc-speedbar--ensure): Create `speedbar-buffer' when needed, and
delete the original frame, but still keep a reference to it in
`erc-speedbar--hidden-speedbar-frame'. Set
`dframe-delete-frame-function' to own handler.
(erc-speedbar--shutting-down-p): Remove unused variable.
(erc-speedbar--run-timer-on-post-insert)
(erc-speedbar--prod-dframe-timer): Rename former to latter. Return
nil, and accept any number of args.
(erc-nickbar-mode, erc-nickbar-disable): Tear down completely when
disabling, regardless of universal argument. This changes user-facing
behavior that was originally introduced with this module as part of
bug#63595. Run `erc-speedbar--prod-dframe-timer' on
`erc-server-PONG-functions' as well as `erc-insert-post-hook' so that
the panel will eventually update if no messages are being received.
(erc-speedbar--dframe-controlled): Don't make frame visible because
it's been deleted and was never made invisible.
* test/lisp/erc/erc-scenarios-status-sidebar.el
(erc-scenarios-status-sidebar--nickbar): Update assertions.
* etc/ERC-NEWS: Mention that certain aberrant response handlers now
return nil.
* lisp/erc/erc-backend.el (define-erc-response-handler): Mention that
body should explicitly return nil.
(erc-server-PART)
(erc-server-PING): Return nil.
* lisp/erc/erc-sasl.el (erc-sasl--destroy): Return nil.
* lisp/erc/erc.el (erc-display-message): Mention in doc string that
the return value is undefined.
(erc-kill-channel-hook): Fix package-version.
* test/lisp/erc/erc-networks-tests.el (erc-networks--set-name): Ensure
`erc--route-insertion' returns nil because this influences whether
response-handler hooks continue running.
* test/lisp/erc/erc-sasl-tests.el
(erc-sasl-create-client-ecdsa): Fix regression that made test
unusable, although it's still relatively useless and therefore skipped
by default.
* test/lisp/erc/erc-services-tests.el
(erc-services-tests--auth-source-standard)
(erc-services-tests--auth-source-announced): Clarify annotations.
* test/lisp/erc/erc-tests.el (erc-message): Don't return non-nil in
mocked `erc-display-message'.
(erc-send-modify-hook): Shadow `erc-send-modify-hook' because
`erc-stamp--date-mode' modifies it locally.
* etc/ERC-NEWS: Mention new face `erc-information'.
* lisp/erc/erc-button.el (erc-button-add-buttons): Skip buttonization
when the "msg prop" `erc--skip' is present and contains the symbol
`button'. Set `alist' to nil in the same guard condition as a
roundabout way of suppressing further processing.
* lisp/erc/erc-networks.el (erc--insert-admin-message): Forward
declaration.
(erc-networks--insert-transplanted-content)
(erc-networks--transplant-buffer-content): Replace former with latter.
Change signature to take source and destination buffers as parameters.
(erc-networks--transplant-target-buffer-function): New function-valued
variable.
(erc-networks--target-transplant-in-progress-p): New variable, a flag
for downstream code to detect when a transplant is underway.
(erc-networks--reclaim-orphaned-target-buffers): Defer to
`erc-networks--transplant-target-buffer-function' to handle the actual
transplant business. Crucially, kill the buffer afterwards instead of
beforehand. If new buffer-association bugs emerge related to the
combining of old or renamed target buffers, this reordering may be at
fault.
(erc-networks--copy-over-server-buffer-contents): Pass old and new
buffers to `erc-networks--insert-transplanted-content'.
* lisp/erc/erc-stamp.el
(erc-stamp--defer-date-insertion-on-post-modify): Set `fn' slot of
`erc-stamp--date' instance to `ignore' when running the actual
callback in order to conserve a little space.
(erc-stamp--date-mode): Add and remove hook members for
`erc-networks--copy-server-buffer-functions' and
`erc-networks--transplant-target-buffer-function'.
(erc-insert-timestamp-left-and-right): Always clear
`erc-timestamp-last-inserted-right' to ensure a right stamp
accompanies every date stamp.
(erc-stamp--dedupe-date-stamps)
(erc-stamp--dedupe-date-stamps-from-buffer)
(erc-stamp--dedupe-date-stamps-from-target-buffer): New functions.
Date stamp behavior was revamped as part of bug#60936.
* lisp/erc/erc.el (erc-informational): New face.
(erc--insert-admin-message): New function to hide some "msg prop"
complexity from "upstream" libraries, like `erc-networks', and thus
avoid more forward-declarations. A less smelly approach would be to
devise a general interface owned by such libraries, or erc-common,
that `erc-mode' could then hook into on init.
(erc-display-message-highlight): Make face matching more limber to
accommodate the convention of face names lacking a "-face" suffix.
(erc-message-english-graft): New variable.
(erc-kill-channel): Inhibit execution of hook when
`erc-networks--target-transplant-in-progress-p' is non-nil.
* test/lisp/erc/erc-networks-tests.el

New test. (Bug#70928)
* etc/ERC-NEWS: Mention new flag `erc-killing-buffer-on-part-p' and
the renaming of `erc-kill-channel'.
* lisp/erc/erc-backend.el (erc-server-PART): Only kill a buffer on
behalf of `erc-kill-buffer-on-part' when the buffer hasn't already
been killed, and bind `erc-killing-buffer-on-part-p' to t when doing
so.
* lisp/erc/erc-log.el (erc-conditional-save-buffer): Don't save logs
when the buffer parameter is nil because that causes the server buffer
to be saved out. It's possible that user code relying on this
longstanding bug will be affected, however, by default, the server
buffer will also be saved out independently at designated junctures.
* lisp/erc/erc.el (erc-part-hook): Redo doc string.
(erc-killing-buffer-on-part-p): New variable, a flag to prevent
redundant execution of `erc-kill-channel-hook' members concerned with
parted channels.
(erc-kill-buffer-on-part): Tweak doc string.
(erc-kill-channel-hook): Use new name for `erc-kill-channel',
`erc-part-channel-on-kill'.
(erc-kill-channel, erc-part-channel-on-kill): Rename former to latter,
and inhibit execution when `erc-killing-buffer-on-part-p' is non-nil.
* test/lisp/erc/erc-scenarios-base-kill-on-part.el: New file.
(Bug#70840)
* lisp/erc/erc.el (erc-once-with-server-event): Set hook depth to -95.
* test/lisp/erc/erc-scenarios-base-association-nick.el: Improve
comment.
* test/lisp/erc/resources/erc-d/erc-d-tests.el
(erc-d--render-entries): Remove do-nothing assertion since its purpose
was unclear and likely dubious, as was incidentally highlighted by the
addition of a function not present on older Emacsen, which this test
still needs to run on.
Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.
* src/eval.c (Fmake_interpreted_closure): New function.

more precise type info in `describe-function`.

Use `interpreted-function-p`.
* test/lisp/emacs-lisp/macroexp-resources/vk.el (vk-f4, vk-f5):
Don't hardcode function values.
* doc/lispref/functions.texi (Anonymous Functions): Don't suggest that
function values are lists. Reword "self-quoting" to reflect the
fact that #' doesn't return the exact same object. Update examples
with the new shape of the return value.
* doc/lispref/variables.texi (Lexical Binding):
* doc/lispref/lists.texi (Rearrangement):
* doc/lispref/control.texi (Handling Errors): Update examples to reflect
new representation of function values.
* lisp/erc/erc.el (erc-server-or-unjoined-channel-buffer-p): Doc.
(erc-query-buffer-p): Don't return non-nil in non-ERC buffers and
server buffers, and continue to honor string arguments. The
regression was introduced by 3d87e343 "Use modern fallback for channel
name detection in ERC". Thanks to Libera user mekeor for reporting
this bug.
* test/lisp/erc/erc-tests.el (erc-query-buffer-p): New test.
(Bug#67220)
* lisp/erc/erc-backend.el (erc-server-connect): Add `erc--skip'
property to `erc--msg-prop-overrides' so that timestamps only show up
with the first server-sent message.
(erc-server-PRIVMSG): Move `erc--msg-prop-overrides' declaration to
top-level.
* lisp/erc/erc-button.el (erc-button--display-error-notice-with-keys):
Use `erc--skip' msg prop instead of `erc-stamp--skip' variable.
* lisp/erc/erc-stamp.el (erc-stamp--skip): Remove variable.
(erc-stamp--allow-unmanaged, erc-stamp--allow-unmanaged-p): Rename
former to latter to remain consistent with convention used by other
quasi-internal compatibility-related switches.

* lisp/erc/erc-fill.el (erc-fill-wrap): Don't move last-message marker
when encountering a date stamp.
* lisp/erc/erc-stamp.el (erc-stamp--recover-on-reconnect): Restore
`erc-stamp--date-stamps' on reconnect and rejoin.
(erc-stamp--insert-date-hook): Fix erroneous doc string.
(erc-stamp--date): New struct type.

between hook members.
(erc-stamp--date-stamps): New internal variable to store a reference
to all inserted timestamps.
(erc-stamp--propertize-left-date-stamp): Don't hide messages because
this function runs on `erc-insert-modify-hook'. Prefer doing so
later, in `erc-insert-post-hook'.
(erc-stamp--find-insertion-point): New helper function.
(erc-stamp--insert-date-stamp-as-phony-message): Remove.
(erc-stamp--lr-date-on-pre-modify): Remove function. Portions of body
now appear in `erc-stamp--defer-date-insertion-on-post-modify'.
(erc-stamp--defer-date-insertion-on-post-modify)
(erc-stamp--defer-date-insertion-on-post-insert)

although the first incorporates parts of the now defunct
`erc-stamp--lr-date-on-pre-modify'.
(erc-stamp--date-mode): Update hook-member functions.
(erc-stamp-prepend-date-stamps-p): Revise doc.
(erc-insert-timestamp-left-and-right): Remove code to initialize a
date stamp in place through a nested call to `erc-display-message'.
Instead, "pre-render" date stamp and stash it for retrieval by
the function `erc-stamp--defer-date-insertion-on-post-modify'.
(erc-stamp--setup): Kill variables `erc-stamp--deferred-date-stamp'
and `erc-stamp--date-stamps'.
(erc-stamp--reset-on-clear): Remove trimmed stamps from
`erc-stamp--date-stamps'.
* lisp/erc/erc.el (erc--msg-props): Document `erc--hide' in doc
string.
(erc--with-inserted-msg): Remove unused macro.
(erc--insert-line-splice-function): New variable.
(erc--with-spliced-insertion): New macro.
(erc--insert-line-function): Expand doc string.
(erc--remove-from-prop-value-list): Tweak doc string.
(erc--insert-before-markers-transplanting-hidden): New function.
(erc--hide-message): Remember managed `invisible' prop value. Do so
by recording them in the `erc--hide' "msg prop".
(erc--delete-inserted-message, erc--delete-inserted-message-naively):
Rename former to latter to emphasize that it's largely impractical for
general use.
(erc--ranked-properties): Add `erc--hide'.
* test/lisp/erc/erc-button-tests.el
(erc-button-tests--erc-button-alist--function-as-form): Use
`erc-display-message' helper.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--insert-privmsg)
(erc-fill-tests--wrap-populate, erc-fill-wrap-tests--merge-action)
(erc-fill-line-spacing): Use `erc-display-message' wrappers to
intercept `erc-timer-hook' modifications.
* test/lisp/erc/erc-scenarios-match.el
(erc-scenarios-match--invisible-stamp): Add convenience commands to
`extended-command-history' when running interactively.
* test/lisp/erc/erc-tests.el
(erc--insert-before-markers-transplanting-hidden): New test.
(erc--delete-inserted-message, erc--delete-inserted-message-naively):
Update test name as well as namesake function in body.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-common-with-cleanup): Validate `erc-stamp--date-stamps'
members after every scenario test.
(erc-scenarios-common--assert-date-stamps): New function.

atop file when compiling.
(erc-tests--common-display-message)
(erc-tests-common-display-message)
(erc-tests-common-with-date-aware-display-message): New functions and
macro for running `erc-display-message' while intercepting additions
to `erc-timer-hook' made by date-stamp-related post-insertion hooks.
(erc-tests-common-snapshot-compare): Insert expected output into its
own buffer for easier review during interactive sessions. This change
is unrelated to the rest of this commit. (Bug#60936)
* lisp/erc/erc-fill.el (erc-fill--wrap-escape-hidden-speaker): Add
parameter to suppress escaping of hidden prefixes.
(erc-fill--wrap-beginning-of-line): Remember original value of point,
and pass it to `erc-fill--wrap-escape-hidden-speaker'.
(erc-fill--wrap-previous-line, erc-fill--wrap-next-line): Guard call
to `erc-fill--wrap-escape-hidden-speaker' with conditional check for
`erc-fill-wrap-merge'.
(erc-fill--wrap-insert-merged-pre): Add additional text property,
`erc-fill--wrap-merge', to help identify `display' regions servicing
`erc-fill-wrap-merge'. This should make resolving inconsistencies
easier when "splicing" new messages between existing ones.
(erc-fill-wrap): Add `erc-fill--wrap-merge' text property to merged
speaker region.
(erc-fill--wrap-rejigger-region): Remove assertion disallowing a
non-nil `erc-fill--wrap-rejigger-last-message'. Instead, adopt the
existing value of that variable when shadowing it for the remaining
extent of the function's execution. When removing the `display'
property, also look for nonempty replacement text, such as values
specified by the option `erc-fill-wrap-merge-indicator'.
(erc-fill--wrap-merged-button-p): Look for `erc-fill--wrap-merge'
property instead of `display'.

(Bug#60936)
* lisp/erc/erc-fill.el (erc-fill-wrap-merge-indicator): Reduce
offering of acceptable values by removing leading symbols and ditching
the `post' variant entirely. The justification for the latter move
hinges on it not being well suited to next-gen requirements involving
the splicing and deletion of inserted messages. Meeting these would
be overly burdensome and involve scanning the buffer in both
directions for every such operation. This option is new in ERC 5.6,
which is yet unreleased.
(erc-fill--wrap-massage-legacy-indicator-type): New function to warn
of obsolete `erc-fill-wrap-merge-indicator' value and perform a
migration for the current session.
(erc-fill-wrap, erc-fill-wrap-enable): Preform preflight compat check
for obsolete `erc-fill-wrap-merge-indicator' value types.
(erc-fill-wrap-disable): Don't bother killing nonexistent variable
`erc-fill--wrap-merge-indicator-post'.
(erc-fill--wrap-merge-indicator-post): Remove unused variable.
(erc-fill--wrap-insert-merged-post): Remove unused function.
(erc-fill--wrap-insert-merged-pre): Adapt to simplified format for
option `erc-merge-wrap-merge-indicator'.
(erc-fill-wrap): Remove conditional dispatch because there is only one
path and only one indicator style.
(erc-fill--wrap-rejigger-region): Remove reference to nonexistent
variable `erc-fill--wrap-merge-indicator-post'.
* test/lisp/erc/erc-fill-tests.el
(erc-fill-wrap--merge-action/indicator-pre): Update format of value
for option `erc-fill-wrap-merge-indicator'.

obsolete and unsupported `post' variant of option
`erc-fill-wrap-merge-indicator'.

alternate method for upgrading from GNU ELPA. This is a partial
workaround for bug#68660 discovered by ERC contributor Alcor.

(erc-scenarios-base-renick-queries-bouncer): Adjust timeout.
* lisp/erc/erc.el (erc--read-time-period, erc--decode-time-period):
Move body of former, now a superficial wrapper, to latter, a new
function.
(erc--format-time-period): New function.
(erc--get-ignore-timer-args): New function.
(erc--find-ignore-timer): New function to search through `timer-list'
to find matching ignore timer.
(erc-cmd-IGNORE): Refactor and redo doc string. Add new optional
`timespec' parameter, primarily to aid in testing. Update an existing
timer instead of always creating one, and display time remaining in
"ignore list" output. Pass server buffer instead of current buffer to
timer callbacks because `erc--unignore-user' displays its messages in
the `active' buffer, not necessarily the issuing one. Note that doing
this does discard potentially useful information, so if ever reverting,
we can change the `cl-find' :test in `erc--find-ignore-timer' to
something that compares the `erc-server-process' of both buffers.
;;
;; Something like:
;;
;; (defun erc--ignore-timers-equal-p (a b)
;; (and (equal (car a) (car b))
;; (eq (buffer-local-value 'erc-server-process (cadr a))
;; (buffer-local-value 'erc-server-process (cadr b)))))
;;
(erc-cmd-UNIGNORE): Pass `erc-ignore-list' member matching `user'
parameter to `erc--unignore-user' instead of original, raw parameter,
along with the server buffer.
(erc--unignore-user): Cancel existing timer and don't bother switching
to server buffer since we're already there.
(erc-message-english-ignore-list): New variable.
* test/lisp/erc/erc-scenarios-ignore.el: New file.
* test/lisp/erc/erc-tests.el (erc--read-time-period): New test.
(erc-cmd-UNIGNORE): New test. (Bug#70127)
* lisp/erc/erc-stamp.el (erc-insert-timestamp-right): Insert a single
space character immediately before right-side stamps managed by
`erc-stamp--display-margin-mode'. Include it as part of the
`timestamp' field. This behavior was originally present in an earlier
draft of the changes for bug#60936, mainly to favor symmetry between
hard-wrapped fill styles and fill-wrap with regard to stamps. It was
subsequently removed to simplify management, so that the `field' and
`display' intervals aligned.
* test/lisp/erc/erc-stamp-tests.el
(erc-stamp--display-margin-mode--right): Update expected output.

`:inverse-video' (née :reverse-video) to swap foreground and
background colors over affected intervals, as per
https://modern.ircdocs.horse/formatting#reverse-color.
(erc-control-default-fg erc-control-default-bg): New faces for IRC
color-code number 99. Ignore the ERC convention of prefixing
control-code-derived faces with "fg:" and "bg:" because it doesn't
comport with modern sensibilities, which demand identifiers normally
be namespaced.
(erc-get-bg-color-face, erc-get-fg-color-face): Return new, dedicated
faces instead of `default', and don't nest them in a list.
* test/lisp/erc/erc-goodies-tests.el
(erc-controls-highlight--inverse): Redo completely, asserting behavior
described in the spec linked to above.
(erc-controls-highlight--spoilers): New test based on the body of the
old `erc-controls-highlight--inverse', except without shadowing
`erc-insert-modify-hook' with an unrealistic, idealized value. Adjust
expected buffer state to reflect the new role of
`erc-spoiler-face'. (Bug#69597)

(erc-channel-p): Refactor and use `erc--fallback-channel-prefixes' for
the default CHANTYPES value. Honor an empty CHANTYPES value as valid,
e.g., for servers that only support direct messages.
(erc--fallback-channel-prefixes): New variable to hold fallback
CHANTYPES prefixes recommended by RFC1459 and modern authorities on
the matter.

ignored, and exit early when entering a minibuffer.
(erc--keep-place-indicator-setup): Remove function because local
modules don't need a separate setup function.
(erc-keep-place-indicator-mode): Add autoload cookie even though this
is a local module, since this particular one is intended for more
granular, interactive activation. This is mostly a formality because
it only matters in the unlikely event `erc-modules' is missing all
other modules defined in `erc-goodies'.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable,
